Abstract (en)

[origin: WO2013142968A1] Described herein are compositions comprising at least one auxin transport inhibitor for pre-treating a plant or seed to increase saccharification, or saccharide release by hydrolysis, the at least one auxin transport inhibitor being in an amount effective to increase sugar release from a plant tissue by hydrolysis. Also described are plant mutations, and methods to screen for such plant mutations, having an improved sugar release phenotype. The described compositions, methods and plant mutations are particularly useful for producing biofuel crops, such as maize, to improve sugar extractability from lignocellulosic biomass and hence, the efficiency of bioethanol production overall.
